FIREPROOF FIXTURE.

Specification of Letters Patent.

Patented March 27, 1906.

Application filed March 31. 1905. Serial Noi 253,051.

.To a/Zi whom, t nmy concern,.-

Bc it known that l, EUGENE l". Frrzrii'r- RICK, n citizen of the UnitedStates, and a resident of the city of Non' York, borough of Brooklyn, intho county nl Kings and State of New York, have invented a new andlinproved Fireproof Fixture, ol which the lollowing is a full, clem',and exact description.

My invention relates to lireproof fixturessnch as partitions, blinds,doors, walls, and the lil e--111y more particular purpose being toprovide an inclosed hir-space, sometimes designe-ted as a vac-noni,which acts as s. non-conductor of lient.

Incidental to this purpose my invention further consists in certainconstructionai details and combinations ci' parts hereinaterl described,and pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters ci reference indicatecorresponding parts in ail the ligures.

Figure i is zi frsginentery iront elevation showing a partition equippedwith iny invention. Fig. 2 is a horizontal section showing the manner ofsecuring and spacing the front and back walls. Fig. 3 is o. horizontalsection through a pair of shutters equipped with my invention, and Fig.4 is a vertical section through one of the shutters.

A number of separate plates 5 5a 6 6 of lsheet metal, preferably ironJare connected together by means of Z-bars 7 of the form shown. Theplates 5 5 are in alinement with each other, as indicated in Fig. 2, andare connected together by angle-strips 8, each provided with anair-space S and heid against the adjacent plates by meansof bolts 9,provid ed with nuts 10. Between the pairs of plates 5a oa are spaces 1111, filled with air, which serves as a non-conductor of heet.Angle-irons 12 13 ere secured upon opposite sides of the plates 5a 6'*end are used for connecting these plates with other plates 5b 6b, so asto form angles, as indicated at the right of Fig. 2. Bolts 14 areemployed for the purpose of connecting the angle-plates toether adjacentto the edges of the plates 5 6a 515 6b. The angle-plates are separatedby air-spaces 12a. scribed every part which would otherwise be liable totransmit the heat in case of s. re is in the construction just de:A

prevented from so doing by virtue of one or more air-spaces. Even thejoints are as far es possible provided with air-spaces.

it will be noted that as the plates 5 5a 6 6 iney be :nado of dilerentwidths and of different heights the partition indicated in F ig. 2 maybe lengthened, shortened, widened, or narrowed at will. It will also benoted that each Z-bar 7 serves as e post and also as a fastening for thebolts 9 as weil as acting in the capacity of a subpartition separatingad- `ioining air-spaces, such as 11 lig. No boltholes are necessary, forthe reason that the plates 5 5l and the plates 6 6a do not abut eachother edgewse, but are disposed in juxtaposition upon opposite sides ofthe bolts 9 and are separated by a space representing the thicknessofsuch a bolt. It is this specie or crack (indicated in Fig. 1 at 9*)which is covered by the strip 8.

In Fig. 3 a pair of shutters are shown. The walls of the building areshown at 15 16 and the front and back plates of the shutter are shown at17 18. These plates are paired, as shown, andconnected by Z-bars 19 20,held in position by "ineens of bolts 21. Hinge members 22 are rnoii'ntedupon hinge-bestrings 23 andsecured to the front piate i7 by ineens ofbolts 24. A`il`ange 25 is secured by bolts Z6 upon one of the frontplates 17, and Similarly a iienge 27 is secured by bolts 2S upon one ofthe back plates 18, as will be nderstood from Fig. 3. The top of eachshutter, es shown in Fig. 4, is closed by a Z-bar 29, the upper portionof which is riveted to the up er edge 17 of the front plate, the beckplate 18 being'riveted upon the lower portion of the ,Z-barii.V ;Eac ishutter contains an air-s ace 30.

Shuttersyinade as above described are comparatively light, eachconsisting of a composite hollow shell provided with en airspace, endowing to the shape of the Z-bars 19 20 each shutter fits snngiy aroundthe corner of the wall 15 16, ipon which it is free to swing, asindicated in ig. 3.

1t is impracticabe to describe all of the various forms in which myinvention may be used. Suffice it to say that I do not limit rnyselt` tothe construction above described, and many forms differing slightlytherefrom may be employed without departing from the spirit of myinvention.

Having now described my invention, I

roo

claim as new and desire to secure by Letters Patent- 1. A shutter,comprising a front plate and a back late, Z-bars mounted upon oppositesides opsaid shutter, fastening members for detaehably securing saidZ-bars to said front and said back platesJ and means for mounting saidshutter.

2. In a shutter, the combination of a front plate and a back plate,Z-bars disposed oppositely to each other and intermediate of saidplates, one of said Z-bars having the angular conformity of a wall, anda hinge member connected with one of said plates and with said wall forenabling said shutter to swing as a door.

3. In a shutter, the combination of a front plate and a back plate,members disposed upon opposite edges of said shutter and spac ing saidplates apart, and a Z-bar mounted within the top ed e of said shutterand secured to one of sai( plates, said Z-bar havin a portieri forpartially overlapping a wal above said door.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
